IDC's "Innovative Companies Under $100M to Watch" reports are a qualitative evaluation of a set of vendors within a specific market -- they are not a stack ranking nor do they represent an exhaustive evaluation of all companies in a segment or a comparative ranking of the companies in the report. IDC solicited entries from vendors of less than $100 million that exemplify specific key trends (selected by analysts) that are driving change in a specific software market. Vendors then submitted case studies that exemplified one of the trends used as the basis for the award. These case studies were evaluated individually and independently by related market analysts across several pre-determined criteria. The teams then met to review the scores. The case studies submitted for review had to demonstrate that the technology was available, able to be implemented and provided real-world benefits to the customer.
